Page 11: Compressor Assembly
Check the compressor for transport damage before starting any work. 4.1 Setting up Fittings (e.g. pipe holders, additional units etc.) on the compressor are permissible only following consultation with GEA. Setup on an even surface or frame with sufficient load-bearing capacity. The compressor can be fastened as follows: - using the 4 drill holes on the baseplate - using the 3 side M10 tapped blind holes on the left or right of the compressor housing - using the 4 M10 tapped blind holes on the front of the compressor housing. -

4| Compressor assembly 4.6 Pipe connections The pipe connections have graduated inside diameters so that pipes in the common millimeter and inch dimensions can be used. The connection diameters of the shut-off valves are designed for maximum compressor output. The required pipe cross-section must be matched to the capacity. -

Page 15: Commissioning
5| Commissioning 5.1 Preparations for start-up INFO! To protect the compressor against inadmissible operating conditions, high-pressure and low-pressure pressostats are mandatory on the installation side. The compressor has undergone trials in the factory and all functions have been tested. There are therefore no special running-in instructions. -
Page 16: Refrigerant Charge
5| Commissioning 5.5 Refrigerant charge CAUTION! Wear personal protective clothing such as goggles and protective gloves! ATTENTION! Avoid overfilling the system with refrigerant! To avoid shifts in concentration, zeotropic refrigerant blends (e.g. R407C) must always be added to the refrigerating plant in liquid form. Do not pour liquid refrigerant through the suction line valve on the compressor. It is not permissible to mix additives with the oil and refrigerant. -
Page 17: Avoiding Liquid Shocks
5| Commissioning 5.7 Avoiding liquid shocks ATTENTION! Slugging can damage the compressor and cause refrigerant to leak. To prevent liquid shocks: The complete refrigeration plant must be correctly designed and executed. The capacities of all components must be compatible (particularly evaporator and expansion valve). Suction gas superheating at the evaporator output should be at least 7 – 10 K (check setting of the expansion valve). -
